Browse the registry by cross-cutting compliance TOPIC (for example data breach notification, AI transparency, AML and KYC). Returns each topic with how many rules carry it and across how many pillars and jurisdictions. Topics sit on top of the 39 pillars without replacing them. Free, no key required. Pass a topic string to drill into one.
| Name | Required | Description | Default |
|---|---|---|---|
| topic | No | Optional topic name to filter or drill into. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds behavioral details beyond the readOnlyHint and openWorldHint annotations, such as returning aggregated counts and supporting drill-in via the topic parameter. It explains the conceptual relationship to pillars, which is useful. The mention 'Free, no key required' is redundant with openWorldHint, but the rest adds value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured and front-loaded with the core purpose. It contains five sentences, but one sentence ('Free, no key required') duplicates the openWorldHint annotation and could be removed without loss. Overall, the description is efficient and informative.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read-only tool with one optional parameter, the description covers the essential aspects: what it does, what it returns, and the parameter's effect. It also provides context on how topics relate to pillars. Since there is no output schema, the description's mention of 'how many rules carry it and across how many pillars and jurisdictions' helps set expectations, though it could mention edge cases like no results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already describes the topic parameter as 'Optional topic name to filter or drill into,' and the description reinforces this with 'Pass a topic string to drill into one.' It also clarifies the default behavior by stating the tool returns all topics when no parameter is passed. The examples of topics add semantic richness beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function: 'Browse the registry by cross-cutting compliance TOPIC' and specifies the output—'each topic with how many rules carry it and across how many pillars and jurisdictions.' It distinguishes itself from siblings like list_pillars by emphasizing that topics are cross-cutting and sit on top of the 39 pillars without replacing them.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context for when to use the tool: for browsing topics rather than pillars or other registry views. It also explains the optional topic parameter, saying 'Pass a topic string to drill into one.' However, it does not explicitly mention alternatives or when not to use it, so it stops short of full explicit guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Most tools have clearly distinct purposes. The few overlapping pairs (get_node vs consult_node, get_latest_changes vs obligation_deltas) are explicitly differentiated in their descriptions, so an agent should be able to select correctly. No tools appear to do the same thing.
The majority of tools follow a clear verb_noun pattern (get_node, create_attestation, seal_run). However, several tools deviate significantly: drift_check and gap_check put the noun first, obligation_deltas is a bare noun, and point_in_time and oscal_assessment_results are noun phrases without a verb. This inconsistency makes the set feel less predictable.
At 25 tools, this is at the heavy end of the range. However, the tool set covers a very broad compliance intelligence domain, including discovery, compliance checks, run management, attestations, and change feeds. Each tool has a clear role, but the sheer number may overwhelm agents that need only a subset of functionality.
The tool surface is very comprehensive for a compliance intelligence platform. It covers discovery (browse, search, list, get), action compliance checking, jurisdiction comparison, dependency analysis, change tracking, run ledger management, attestation creation, and evidence export. There are no obvious dead ends or missing core operations for the stated domain.
